DEVICE FOR CLEANING THE SURFACE OF A WHEEL RIDING AND INCREASING THE CLUTCH OF THE LOCOMOTIVE WHEELS WITH RAILS

摘要

The utility model relates to rail vehicles, in particular to devices for increasing the adhesion of locomotive wheels to rails. The device for cleaning the wheel rolling surface comprises a pneumatic surface recovery unit and a block mounted on the trolley frame. A distinctive feature of the proposed device for cleaning the surface of the wheel is that the block is made of insulating material and contains on the surface facing the wheel, two metal conductive inserts, one of which is connected to one of the poles of the current source, and the second to the opposite pole of the source current. The proposed device for cleaning the surface of the wheel allows you to reduce the cost of repair and operation of the locomotive due to the reduction of the occurrence of sliders on the surface of the wheel when used due to the fact that the passage of current through the contact surface of metal conductive inserts with the surface of the wheel increases the friction coefficient and improves the quality of cleaning of the surface of the wheel . 1 ill.
